Yes! You can use the Mobile App to lock your SNOO on a motion level of your choosing.
When SNOO is running at the motion level in which you’d like it to stay, press and hold the “Play” button for 3-5 seconds until you see the “Pause” symbol appear. This indicates that you’ve successfully locked in the motion level. Your SNOO will stay on this level until you adjust the levels up or down with the App or by pressing the activity button on SNOO.
SNOO will remain on the "paused" level until the baby cries. Then SNOO will react per usual to begin calming baby.
